Stratigraphy of the Pacific margin of West Antarctica: A contribution to the CASP project
Some of the key parameters in paleoclimate modelling of long time-scales are paleobathymetry of the ocean basins and paleotopography of the continents. Sedimentary thicknesses, rates and formation processes are essential ingredients for deriving paleobathymetry. As part of the Circum-Antarctic Strat...
